NBC announced its fall 2013 premiere dates for new and returning series Friday, including an hourlong Season 6 premiere of "Parks and Recreation" filmed in London followed by back-to-back episodes of the new sitcom "Michael J. Fox Show."

Both shows will debut on Sept. 26. In his new series, Fox stars as a father and husband returning to work as a news reporter in New York after a brief leave of absence to get his Parkinson's under control. Fox lives with the disease.

The two-hour premiere of "The Voice" on Sept. 23 will reunite original coaches Christina Aguilera, CeeLo Green, Adam Levine and Blake Shelton. It will be followed by the series premiere of "The Blacklist," which stars James Spader as an international criminal who works with a rookie FBI agent in order to bring down some of the world's most wanted.

"Grimm" returns to Fridays beginning Oct. 25, and will be paired with new drama "Dracula," starring Jonathan Rhys Meyers as the iconic vampire who now lives in Victorian England where he seeks revenge on those who doomed him to immortal hell.

"Star Wars Rebels" continues to offer up gifts for the fans. On Monday's first-season finale, it reintroduced the beloved character Ahsoka Tano from "The Clone Wars" animated series. Now it's recruiting a former vampire slayer.
